Definitions
- one of the main concerns in designing RO systems is to provide a process design that eliminates or minimizes RO membrane fouling.
- the present system and process is designed to eliminate, or at least minimize, membrane fouling of the RO units 30 and 36.
- the organics are removed by the DAF, MPPE, and MBR units.
- Scaling potential due to calcium carbonate is substantially reduced by the addition of the sulfuric acid and can be further controlled by an anti-scalant feed.
- Iron and aluminum have also been removed upstream from the RO units 30 and 36. This leaves as the major concern, silica.
- the solubility of silica is about 120 ppm in neutral water.
- the produced water generally has as much as 70 ppm of silica.
